Dependency Analysis Patterns

Dependency Graph Visualization

# npm
npx depcruise --output-type dot src/ | dot -T svg > deps.svg

# Python
pipdeptree --graph-output svg > deps.svg

# Go
go mod graph | modgraphviz | dot -T svg > deps.svg

Circular Dependency Detection

# JavaScript/TypeScript
npx madge --circular src/
npx dpdm --circular src/index.ts

# Python
pydeps --cluster --no-show src/

Fix Strategies

| Circular Tip | Çözüm | |-------------|-------| | A → B → A | Interface/port ile inversion | | A → B → C → A | Shared module extract et | | Barrel file circular | Direct import kullan |

CVE Scanning

# npm
npm audit --json | jq '.vulnerabilities | to_entries[] | select(.value.severity == "critical")'

# pip
pip-audit --format json --desc

# Go
govulncheck ./...

# Multi-tool
trivy fs --severity CRITICAL,HIGH .

CVE Prioritization

| CVSS | Severity | Aksiyon | SLA | |------|----------|---------|-----| | 9.0+ | Critical | Hotfix | 24h | | 7.0-8.9 | High | Sprint fix | 1 hafta | | 4.0-6.9 | Medium | Backlog | 1 ay | | <4.0 | Low | Track | Fırsatçı |

License Compliance

# npm
npx license-checker --production --json --failOn "GPL-3.0;AGPL-3.0"

# Python
pip-licenses --format=json --fail-on="GPL-3.0"

| License | Commercial OK | Copyleft | Risk | |---------|-------------|----------|------| | MIT | Evet | Hayır | Düşük | | Apache-2.0 | Evet | Hayır | Düşük | | BSD-3 | Evet | Hayır | Düşük | | MPL-2.0 | Evet | Kısmi | Orta | | LGPL | Dikkat | Kısmi | Orta | | GPL-3.0 | Dikkat | Evet | Yüksek | | AGPL-3.0 | Dikkat | Evet | Çok yüksek |

Update Impact Analysis

# npm - outdated
npm outdated --json

# Semver risk
# patch (0.0.x) → güvenli
# minor (0.x.0) → genelde güvenli
# major (x.0.0) → breaking change riski

# Test after update
npm update <pkg> && npm test

Checklist

• [ ] npm audit / pip-audit temiz (critical/high yok)
• [ ] License audit pass (GPL yok)
• [ ] Circular dependency yok
• [ ] Lockfile committed ve güncel
• [ ] Unused dependency yok (depcheck)
• [ ] Renovate/Dependabot aktif
• [ ] Major version behind ≤1

Anti-Patterns

• Audit warning'leri ignore etmek
• Lockfile commit etmemek
• Pinned version kullanmamak (^, ~)
• License check'siz production dependency
• Dependency update'siz 6+ ay
